Last month, residents of (and visitors to) Melbourne’s Federation Square were invited to crawl through a vast network of semi-transparent tubes suspended nearly 20 feet in the air. If that sounds like a carnival ride you’d rather sit out, you won’t be comforted by the fact that the structure was made entirely of packing tape.

Last year, For Use/Numen, an Vienna-based artist collective, installed a suspended network of tunnels made out of 100 pounds of clear packing tape. Visitors were invited to climb into and crawl around in the structure, which resembled the work of hearty silkworms. (Read more about the Tape project here.) Building on that success, For Use has created another interactive public sculpture, this time using layers of flexible netting held in midair.
